f This invention relates generally to turntables for-use in garages, orvehicle service stations, for` supporting motor vehicles, andr haslparticular reference tol a superstructure'. for use with: an hydraulicyor pneumatic ele-VK vator, although vobviously the superstructure maybe usedasafpart oflan kordinary turn- One object character Which visformed, inpart, of a rein# Another object of the invention is 'theprovision of a superstructure for motor -veh1cle *lifts Which includes4a pressedmetal head adapted to be supportedl by the upper end ofapistonof an hydraulic or pneumatic lift.

A further object of theinvention is the provisionof a superstructure fora vehicle lift Which includes 'spacedrails secured to vand ysupported bya pressedfmetal head, a

portion of which latter ris formed to provide a center bearing;`

ture formed cfa ysingle pressing.

i A. 'further object of the invention is the a lprovisionof aturntablefor motor vehicles Which is simple to manufacture and strong and,`durablefin operation.

, Otherobjects and advantages of thisinvention `Will be apparent fromthe following de -scription taken in conjunction'with the ac-4 com aninv drawinvsin Which:i

v t the present time, hydraulic or pneumatic alifts are 1n use forservicing motor vehicles,

of the'present invention is the provision of a device oftheabovementioned the same being provided With a superstrucf ram and theattachment thereto of the 'superstructure;

Referring noW more-particularly to the rdrawings in which similarcharacters of reference designate similar parts in` the several views,in Figs. l and 2 there is shown a superstructure, indicated generally atA, mounted on the end of a ram B of an hydraulic lift of any preferredconstruction, Which includes a fixed casing cylinder C embedded in theearth. In the instance shown in the drawings, the ram Bis hollow and isguided Vin cylinder C by the depending flange 2 of a guide casting,indicated generally at 4, Which flange is arrangedinteriorly of thecylinder C and adjacent the upper end thereof. The guidecasting 4includes an upper end 6 Which is offset with respect to the iange 2v andwhich has an annular attaching Hangs, 8 adjacent the flange 2 by whichthe casting is connected to the cylinder C through the medium of bolts10 extending through said iange and through an angle ring 12 permanentlysecured to the cylinderC by being Welded thereto, as shown at 14. Ifdesired, a gasket 15 is introduced `betvveen the flange 8, and the angle12, as

clearly shown in Fig. 1. As before mentioned, the castingr 4 includesthe offset portion 6 and this defines a recess Within Which packing 16is received, and the upper end of the offset portion 6 is marginallyflanged, as at 18, Which Harige 18 receives attaching 'bolts 20 Whichextend through the horizontal portionof a n packing gland 22 for anobvious purpose. v Y.

Secured Within the upper end of the ram B, ata little distance from theupper edge thereof, is a head 24Welded, asat 25, to the interior of theram; vthe headv 24 thus closing the upper end of the ram, as Will beapparent.

Permanently secured to they upper end of the ram is a superstructuresupport compris= f ing an attaching plate 26 of greater size than thecircumference of the ram, which plate is permanently secured to a platesupport 28.

in the form of an angle ring by being annularly welded to said ring, asshown at A30. As clearly shown in Fig. 1, the horizontal leg 82 of theyangle ring 28 is arranged above the end of the ram and is permanentlysecured to the ram by being welded to the upper edge support justdescribed is the vehicle supporting superstructure A, which comprises,in the main, a head consistingof a single plate 42 of substantiallyrectangular-form having parallel side edges 44, which may be flanged ifdesired, as shown at 46, for reinforcing purposes. The ends 48l of theplatehave rails 50 n.securedthereto by rivets 52; 'the particulardescription-.of the railsappearinghereinafter.

Initially the head 42 isa single plate, yas before mentioned, andsaidvhead comprises a single pressing, the plate being pressed to theform showny clearlyin Figs. l and 2, thereby providing a Icentralenibossment 54k defining a center bearing 56 (see Fig. l) which in formis adapted to lit over. theplate 26 andto be detachably secured theretoby suitable fas- =teners, such as thebolts 58. Obviously, the

center bearing mayiassume, in outline, any desired form; for example, itmay be circular,

rectangular or Octagon shape depending upon the contour ofthe plate^26.Y f

The central embossinent 54 includes theoppositely extending portions v59which taper Y downwardly in kheight from the center bearing-56 towardthe ends ofthe plate .42`and fade into saidpla-te 42 adjacent theinneredge ofthe base or webnof the railsf50, and" the sides 60 ofsaidembossinent 52k converge towardthe ends offthegplate. yIn otherwords, the embossment comprises a centralportionz forming a centerbearing and gradually rvdi-y minishing portions vextending yoppositely;k

therefrom and terminating inside of the ends ofthe plate 42. As beforementioned, the ends ofthe plate 42 areY designed to support the railsv50j, and, to reinforce saidlends, the plate' is provided Ywithdepending ribs 62 arrangedL on each side of ythe tapering portions 59.rofl the embossment 54 and extending to the ends Y of said plate 42. The,drawings;disclosel the ribs 62 as corrugations formed in theyplate, but,obviously, within thespiritandgscope of the present invention, theplatemay beprol.,

vided with independent reinforcing members if desired.; Asclearly shownin,Fig.2'the ribs 62 'extendjfrom the. ends of the plate42 lpartiallyalong theK tapering portions 59 of the embossment 54 and said ribs 62,as shown in Y Fig. l, diminish in depth near the inner ends thereof, asshown at 64, and fade into the f i plate 42Kat 66 in Fig.'2. VF orreinforcing the vplate 42,'angles68v are secured to the 'lower surfaceVof the plate adjacent the inner ends ofthe ribs 62. It will beyapparent that the ribs 62, in addition to reinforcing Ythe plate,

also serve to supportthe superstructurek when the ram B is in `,itslowered position; the ribs 62 being adapted to Contact with the earth,as shown clearly in Fig. 1.

As before mentioned, the head 42 supports the-spaced railsO, and nowreferring to Figs. l and 2, it can be seen that the rails 50 are 8osubstantially channels ,ha-vingaweb 70 and inner and outer chords72gand7 4, 'respectively, `which chords areprovided with horizontal lianfres76 and?- 8 res ectivel forreinforcinoA 3 5 p y? D the rails, as will beobvious.f Extending 7trans- Y versely across the head 42 andsecuredtherefr to by rivets 80, are angles 82, onellegg-of each .l f

of which is riveted to the chords 72 of the,V 1 Y rails, as shown atv84. v v

ln the form of superstructure shown in Fig.

2, the ends vof thefrails 50 are outwardly flared and downwardly bent toprovide approaches to permit the wheels of/a motor vehicle to easilypass 'onto thelrails 50g-the ends being bent a suiiicient distance torest on the surface of theearth when the ramB vis in lowered position. f

Figs. 8, 4-and5 disclose one end of a modified form of rail 50andwhichis devoid of the integral approach shown in Fig. 2, but-is pro-`Vvided-with a pivoted approach, indicated gen- Y erally at 86, the sainevcomprisingy generally; a

channel section 88 adapted to .underlie the end of rail 50Y andhavingthe chords thereof flanged at 90 to underlie .the flanges 76 and78 of the rail 50. The` approach 86 is pivotal*`v O5 i ly securedunderneaththeH rail 50 byA spaced bolts 92 extending :through the web 70of rail 50 and through the channel 88 and wear-plate 94; bushings 96surrounding .the .bolts to .re-H
